I like to work with computers and have written several programs to help to solve problems of physical interest. Here is a list of some of them (in fact, some of them are pretty old):

- I have participated in the ALPS project (Algorithms and Libraries for Physics Simulations)
- Computation of correlators for local chiral conformal algebras
- Correlation functions of a lattice gas with particle input and output at the boundaries via matrix-product states
- A program to simulate the two-dimensional forest-fire model including X11 support
- A program to compute the radius of compactification
*R*describing the*c*=1 bosonic conformal theory which corresponds to the low-energy excitations of an*XXZ*-chain in a magnetic field. The matching is done on the basis of the Bethe-Ansatz solution of the*XXZ*-chain.

WWW access is unfortunately no longer working at the moment

... and some more software of potential interest to physicists:

- Local archive server (e.g. hep-th)

Click here for a .tar-file with the sources of the most recent version

(Some recent improvements in this program are due to other people) - My private `pocket' calculator (including complex arithmetic, sparse matrix algorithms, ...)

... more small programs can be found on the page for my lectures on (sorry, these pages are in German and stop by 2004).
